💖 ice_switch_flash_banks(9) 💖

Okay so this page is from the Kernel API Manual, bestie, and it's all about telling the firmware to switch NVM banks. Let's get into it ✨

🌸 NAME 🌸

ice_switch_flash_banks — tell firmware to switch NVM banks, periodt 💅

---

🦋 SYNOPSIS 🦋

int ice_switch_flash_banks (struct ice_pf *pf , u8 activate_flags , u8
*emp_reset_available , struct netlink_ext_ack *extack );

---

🎀 ARGUMENTS 🎀

• pf — pointer to the PF data structure, literally the main character of this whole function 🫶
• activate_flags — the flags used for the activation command, iykyk
• emp_reset_available — on return, this one indicates if EMP reset is available ✨
• extack — the netlink extended ACK structure, no cap

---

🔥 DESCRIPTION 🔥

So what this does is it notifies the firmware to activate the newly written flash banks, and then it waits for the firmware response. That's the vibe. You're basically sliding a message to the firmware like "hey bestie, activate these banks" and then you're standing there waiting for it to text back 😭💀

---

⭐ RETURN ⭐

Returns zero on success or an error code on failure. Simple as that, fr fr 💯
